Bryan Johnson Hair Protocol

Johnson uses a custom topical formulation that he applies each evening before bed.

This formulation contains evidence-based ingredients for treating male pattern baldness and promoting hair growth.

Johnson uses a custom blend of the following ingredients in his evening topical treatment:

Minoxidil 5%

This vasodilator medication is clinically proven to help regrow hair in some cases of male pattern baldness.

Minoxidil likely works by increasing blood flow and nutrients to hair follicles.

There are tons of products on the market. They all have the same compound, so there’s no need to overspend here.

Bryan Johnson Red Light Laser Cap Routine

Johnson uses a red light laser cap for 6 minutes each morning.

Red light laser caps may help improve hair growth by enhancing cellular energy production in the follicles.

On this site, he mentions using a Capillus.

However, the pro version of this product is currently listed at around $3,000.

We did a deep dive into red light therapy devices and found some more accessible-priced alternatives below.

Bryan Johnson PRP and Dutasteride Injections

Once a month or every three months, Johnson gets platelet-rich plasma (PRP) injections.

PRP contains a high concentration of growth factors from his own blood.

Research indicates PRP injections may stimulate hair growth in some cases of androgenetic alopecia.

Johnson also takes dutasteride.

This blocks DHT similarly to finasteride. The addition of dutasteride likely enhances the hair growth effects of PRP therapy.

He may also receive standalone dutasteride mesotherapy injections between PRP treatments.

Bryan Johnson Supplements for Hair Health

He also takes oral supplements containing ingredients that may support hair growth and quality.


Some research indicates that collagen supplements may support hair thickness and growth.

Collagen contains amino acids like glycine and proline that makeup keratin, a structural protein for hair.

One study found that collagen peptides increased hair growth and density in women with age-related thinning.

Vitamin D

Vitamin D plays several roles in regulating the hair growth cycle and follicle function.

Vitamin D deficiency has been linked to hair loss conditions like alopecia areata.

Vitamin D from the diet or supplements may help maintain healthy hair follicles and prevent shedding.


Antioxidants help counter oxidative stress, which can damage hair follicles and cause deterioration.

Taking supplements with antioxidant compounds like vitamin E, vitamin C, and selenium may support hair health.

However, more research is needed on their efficacy for treating hair loss.

While oral supplements may provide general hair health benefits, they aren’t proven treatments for genetic hair loss conditions.

Bryan Johnson Philosophy on Hair Loss Prevention

Bryan Johnson believes in taking preventative measures rather than waiting for hair loss to progress further.

By using a combination of proven and experimental treatments, he aims to maintain the hair he still has and potentially regrow lost hair.

While his intensive protocol is time-consuming, Johnson has built the treatments into his daily and monthly routines as habits.

This makes maintenance more sustainable in the long term.

However, he acknowledges his regimen may seem overwhelming to start.
